JavaScript/jQuery RangeSelector Methods
This section describes the methods that can be used in code to manipulate objects related to the RangeSelector.
beginUpdate()
Prevents the UI component from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

dispose()
After calling this method, remove the DOM element associated with the UI component:
$("#myRangeSelector").dxRangeSelector("dispose");
$("#myRangeSelector").remove();Use this method only if the UI component was created with jQuery or pure JavaScript. In Angular, Vue, and React, use conditional rendering:
Angular
<dx-range-selector ...
*ngIf="condition">
</dx-range-selector>Vue
<template>
<DxRangeSelector ...
v-if="condition">
</DxRangeSelector>
</template>
<script>
import DxRangeSelector from 'devextreme-vue/range-selector';
export default {
components: {
DxRangeSelector
}
}
</script>React
import React from 'react';
import RangeSelector from 'devextreme-react/range-selector';
function DxRangeSelector(props) {
if (!props.shouldRender) {
return null;
}
return (
<RangeSelector ... >
</RangeSelector>
);
}
class App extends React.Component {
render() {
return (
<DxRangeSelector shouldRender="condition" />
);
}
}
export default App;See Also

Gets the DataSource instance.

getInstance(element)
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the RangeSelector instance found in an element with the myRangeSelector ID:
// Modular approach
import RangeSelector from "devextreme/viz/range_selector";
...
let element = document.getElementById("myRangeSelector");
let instance = RangeSelector.getInstance(element) as RangeSelector;
// Non-modular approach
let element = document.getElementById("myRangeSelector");
let instance = DevExpress.viz.dxRangeSelector.getInstance(element);See Also

render()
Normally, the UI component redraws itself automatically after the browser window is resized. But on rare occasions, you may need to request the redrawing, for example, after the UI component's container is resized. For this purpose, call the render() method.

render(skipChartAnimation)
When the size of a range selector container changes at runtime, the range selector should be redrawn explicitly. To do this, call its render(skipChartAnimation) method.
If your range selector contains a chart in the background, you can specify whether or not to animate it on render. Pass false as the parameter to animate the chart on redraw. Otherwise, pass true or call the render method without parameters.
